have i ordered the wrong 1 with it having 2 inlet pipes or is it ok to use.
thankyou lads

 

Yes does seem strange that is the the feed for the heater or turbo can't remember which perhaps they have made it so you connect both feeds to the housing hence two unions, it defo says it's for the car.

Early 2wd thermostat housings had 2 take-offs, later one a single take-off. The second take-off was for bleeding. Blank off the rear one.

 

As jon says later housings deleted the bleed feature, I normally drill a 3mm hole in the top edge of the stat just to help any air dispel.

thankyou lads again lol,what will be best to blank it off?

 

you could use a piece of silicone hose with a bolt in it secured with a hose clip,
or alternativly(sp) ford did a blanking cap for the pinto and would assume that the cosworth had the same cap, might be worth trying your local dealer!
